NGC 5683 happens to lie near to a spiral galaxy NGC 5682, but they are far apart from each other. Nearby is another galaxy NGC 5689.[5]
Characteristics
NGC 5683 has an active galactic nucleus which presents strong x-rays.[6] It is a Seyfert 1 type galaxy[7][8] and such falls into the Markarian catalogue as Mrk 474, which its core shines in ultraviolet rays.[9] The most accepted theory for this energy source of active galactic nuclei is the presence of an accretion disk around its supermassive black hole. It also shows high amounts of strong emission-lines which are mostly attributed to short-lived star formation in its regions likely restricted to a nuclear disk with its radius less than few hundred parsecs.[10]
Supernova
Type la supernova SN 2002db[11] was discovered on May 18, 2002, in NGC 5683 by a collaboration of astronomers and Reiki Kushida from LOTOSS (Lick Observatory and Tenagra Observatory Supernova Searches).[12] It was positioned 8 arcsecs west and 9 arcsecs north of the nucleus, with a magnitude of 17.6.[13]
